Another possibility not mentioned: blackmail.
Yeah. If they can have it on Roberts, they can have it on anyone.
I think it has more to do with the gopE’s distain for anything Tea Party/conservative related. They (Boehner et al) don’t really give a crap if the Tea Party sputters out and could very well be coconspirators in the efforts to suppress. The establishment needs dismantled but unfortunately is still a majority (reelected the Speaker).
That is what I keep thinking, they are also afraid of the IRS and who knows who else.
best cure for blackmail is to come forth.
